Abstract: A system, including: a roof deck; a plurality of photovoltaic modules installed on the roof deck, each of the plurality of photovoltaic modules having: a solar cell, and a backsheet, where the solar cell is positioned on the backsheet, where the backsheet has a headlap portion, where the headlap portion has a first longitudinal groove and a second longitudinal groove, where the first longitudinal groove is spaced apart from the second longitudinal groove on the backsheet, to define a nail zone between the first longitudinal groove and the second longitudinal groove; and a plurality of fasteners installed so as to penetrate the nail zones of the plurality of photovoltaic modules and the roof deck.

Abstract: A roofing system includes a roof deck and at least one photovoltaic module installed on the roof deck. The first photovoltaic module includes at least one solar cell and a sealant. At least one fastener penetrates the sealant and the roof deck.

Abstract: A system including a plurality of photovoltaic modules and a plurality of roofing shingles installed on a roof deck. Each of the photovoltaic modules includes a plurality of solar cells. Each of the plurality of roofing shingles includes a core layer and a cap layer composed of a first polymer material and having a first surface and a pattern printed on the first surface. The pattern includes a depiction of a plurality of solar cells that extends between the first end and the second end.
